Using a Powered Subwoofer

If you’re using a powered subwoofer and it outputs very
low-frequency sound at a low volume level, it may not be
detected by Audyssey 2EQ

®

Room Correction and

Speaker Setup.
If the “Subwoofer” appears on the “Review Speaker
Configuration
” screen as “No”, increase the subwoofer’s
volume to the half-way point, set it to its highest crossover
frequency, and then try running Audyssey 2EQ Room
Correction and Speaker Setup again. Note that if the
volume is set too high and the sound distorts, detection
issues may occur, so use an appropriate volume level. If
the subwoofer has a low-pass filter switch, set it to Off or
Direct. Refer to your subwoofer’s instruction manual for
details.
